I am currently using a '2WIRE' wireless router, DSL connection but I would like to purchase a new Airport Extreme station.

Can I just simply disconnect my 2WIRE and connect the Airport base station? Do I have to do anything special or is it that simple?

Thanks. I have been reading all sorts on the Apple Discussion boards but it really confuses me with talk of NAT, WPA, WEP, etc. I just want to know if I can connect it and if it will work without me having to go and get a computer science degree.
